A paper titled “A statistical analysis of the impact of advertising signs on road safety” co-authored by G.Yannis, E.Papadimitriou, P.Papantoniou and C.Voulgari is just published in the International Journal of Injury Control and Safety Promotion. An exhaustive review of international literature was carried out on the effect of advertising signs on driver behaviour and safety and a before-and-after statistical analysis with control groups was applied on several road sites with different characteristics in the Athens metropolitan area. The statistical analysis shows no statistical correlation between road accidents and advertising signs in none of the nine sites examined, as the confidence intervals of the estimated safety effects are non-significant at 95% confidence level. This can be explained by the fact that, in the examined road sites, drivers are overloaded with information, so that the additional information load from advertising signs may not further distract them.
